WELCOME TO THE CONVEYOR BELT GUIDE!

Interesting Facts

The large two-pulley-machine for the official testing of the fatigue resistance of conveyor belts and their splices is capable of testing up to around St 14000 belts. Such dimensions are still up in the air though. This huge machine weighs 250 tons.

Get to know an easy, cheap and efficient way to check whether the belt supplied is in accordance with the agreed fire safety requirements.

The ecological advantages of belt conveyors are becoming more and more important..A study of a Mining University reveals interesting facts.

International Mining reported in its October 2008 issue of a new Phoenocord St 10000. Five fully loaded A380 aircraft could be hung on a 2 m wide belt of this type and it would not break. The official tests of the dynamic splice strength at ITA Germany have been passed, and the belt is ready for use.
The strongest conveyor belts so far are operating in Chile.

Have you heard of conveyor belts that negotiate 3D curves? Pipe conveyor belts are getting increasingly interesting, but you must ascertain a reliable manufacturer. Pipe diameters of up to 900 mm are available.

A new standard for conveyor belts used in underground coal mining of the USA has come into force in 2010.

Dear Guest,
The intention of this site is to provide practical information about heavy duty conveyor belts with tensile members made of textile or steel, that normally is not found on commercial web sites. The ConveyorBeltGuide is permanently growing and you will find certain chapters not being completed yet.
You are kindly encouraged to send your comments or questions. With your support this guide will become better for the benefit of all who are working with this great product.

On 15th September 2013, the ConveyorBeltGuide has been online for 10 years.
Thanks goes to everybody contributing to the success of this site!

Takeover
Germany's Continental/ContiTech intends to buy US based Veyance Technologies, as announced on 2014-02-10, creating by far world's biggest conveyor belt manufacturing group.

New standard
The revised DIN 22102 for textile conveyor belts has been published in January 2014.

New revolutionary conveyor belt monitoring system
According to recent media reports, a revolutionary belt monitoring system was launched at "bauma 2013" in Munich. The system is said to detect any deficiencies inside and outside the moving belt and its splices in real time. It automatically triggers alarms or even stops the conveyor as per users' requirements in case of emergencies.

First standard for indentation rolling resistance of conveyor belts - DIN 22123
This first-time standard has been published in October 2012.

One component adhesive
A new kind of adhesive for cold splicing and repairing of conveyor belts has been launched. This one-component glue makes warehousing and dispatch easier, no activation is necessary, errors by wrong dosage of activator are eliminated, there is no vulcanization in the tin.

Draft revised standards published
E DIN 22109-1 (2013) - Solid woven textile conveyor belts for hardcoal underground mining
E DIN 22109-2 (2013) - Two-ply textile conveyor belts for hardcoal underground mining
E DIN 22109-4 (2013) - Two-ply textile belts for hardcoal above ground use
E DIN 22110-3 (2013) -Dynamic splice test
E DIN 22121 (2013) - Textile belt splices for hardcoal underground mining

Are booster drives the way to go?
For decades, intermediate drives in long conveyors - so-called booster or TT drives - have been used to bring down the peak belt tensions, subsequently allowing for smaller belt ratings.
Just recently, some papers promoting this old idea have been published. We also see several new conveyors employing such extra drives.
However, the negative side of additional drives are higher investment, lower availability, more maintenance and faster belt wear.
A smarter way resp. the first choice could be to design the conveyor belts as per DIN 22101 (2002 or 2011 issues) employing state-of-the-art dynamic splice efficiency, reducing the belt rating and bring down costs, also for other conveyor parts, substantially.
A paper called "State-of-the-art long distance conveyor belt design" pulished in Coal Asia Magazine describes this.

Copyright violations
Established belt manufacturers complain about an increaslng number of copyright violations. Some emergent Indian and Chinese belt manufacturers are illegally copying illustrations from brochures and websites and use them for their own publications.
Although well-informed users of conveyor belts will detect such wrongdoings, it is an unprofessional behaviour which should be stopped.
